Additionally, an increase in star formation in Field 1 and Field 2 around 800 Myr ago is consistent with the idea of recent merger of NGC 5128 with a small gas-rich galaxy ([1]}; [2]}; [3]}; [4]}). After log t(yr) \(\sim \)  \(8.5\) , the rate of recent star formation stays constant according to the recent merger which happened around 400 Myr ago ([5]}). Furthermore, NGC 5128 has experienced AGN activity based on the central supermassive black hole (SMBH). There is an acceptable scenario leading to starbursts and AGN activity which is the interaction of gas-rich galaxies during mergers ([6]}).
